I have seen your comments on Kishlansky's book on your blog, A Trumpet of Sedition. This work is identical to his doctoral thesis supervised by David Underdown, a copy of which is in my possession. The text was not rushed into print prematurely.
Its central argument about the post-1646 politicisation of the New Model Army depends on his claim that, prior to that date, the armies of the Long Parliament lacked political interests of their own but this is clearly mistaken as any study, for example, of the 3rd Earl of Essex's army after the autumn of 1642 or of that of Sir William Waller or of the 2nd Earl of Manchester shows. Each of these armies had its own allies and advocates at Westminster and followers or supporters in the capital and relevant counties.
Kishlansky failed to recognise the implications of the works of Hexter and of Valerie Pearl in this respect. Nor should it be taken that the Levellers alone were significant in forming the political and religious attitudes of the New Model Army: the proposals debated at Putney were, as Philip Baker and Elliot Vernon showed, formulated by Henry Marten and his radical London allies rather than by the Levellers.
In any case, by the time Kishlansky's work was written, his argument hardly fitted into the pejoratively-termed 'Revisionist' project of Conrad Russell and his allies: that project focused on overthrowing the Whig-Marxist synthesis embraced by Hill, Stone, Manning and others. Its dominance was, however, mythical since it had already been challenged by figures like Hexter and John Ball in the 1950s.
In Christopher Hill's case, his influence waned rapidly after c.1972 when his model of analysis came under sustained challenge. Kishlansky's thesis and book were incidental to this process rather than central to it. Peter Lake described Kishlansky in September, 2015 as a "contrarian", someone who liked turning old notions upside down. You can see what he means from Kishlansky's study of Parliamentary elections in early modern England or from his last short book on Charles I.
It was this aspect of his approach that appealed to Russell and Morrill. Revisionism itself was, in any event, spent by c.1990 and has long since passed into the pages of secondary works just like the Marxism of Hill and his CPGB colleagues.
